It is the an operon required for the transport and metabolism of lactose some enteric bacteria (Echerichia coli for example). The Lac operon is only activated in the presence of a key molecule. The key molecule is lactose.
From the given options the following best describes the Lac operon:
D. The repressor is freed from the operator when lactose is present.
Answer:
The test cross is shown below
T T
t Tt Tt
t Tt Tt
The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.
For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent. If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.
This is disproven by the study of cells due to plants don't grow food they making by using sunlight are and water and nutrients <em><u>from </u></em><em><u /></em><u />the soil so it cannot produce the soil due to this fact.
